If An Egg Is Not Fertized The Uterus Comes Off Blood Commonly Called Monthly Period.

If an egg is not fertized the uterus comes off blood commonly called monthly period.

 

Answer:

If the egg does not become fertilized as it travels down the fallopian tube on its way to the uterus, the endometrium (lining of the uterus) is shed and passes through the vagina (the passageway through which fluid passes out of the body during menstrual periods, also called the birth canal), a process called menstruation.
